Diverse types of stress situations are generated by intensive agricultural practices, and all of them are affecting the functionality/productivity of both agricultural systems and natural ecosystems, and therefore, restrict various ecosystem services.

A meta-analysis of global fungal distribution reveals climate-driven patterns. Shifts in microbial community structure and the abundance of various plant-beneficial and detrimental soil microorganisms have been shown to influence the productivity and stability of the agroecosystems [21]. The predominance of Streptomyces (Actinobacteria) in both NT and CT may be due to their ability to produce spores, which might have helped them to survive under both conditions [23]. Several improved agricultural technologies have been adopted for enhancing productivity without taking the sustainability of the system into account. Buyer J.S., Roberts D.P., Russek-Cohen E.

Soil is a hyper-heterogeneous environment and disentangling the factors that shape soil microbial community composition requires an understanding of the broad range of spatial scales involved, before any predictions about functioning in a future climate can be made (Averill et al. The root exudates from plants in certain sets of conditions can favor the establishment of a distinct rhizosphere microbial community by providing wide yet specific varieties of carbon sources [57]. Organic carbon and nitrogen decomposition rates and multifunctionality also significantly decreased by afforestation, and microbial carbon limitation significantly increased in deep soils.

However, organic farming did not affect soil biodiversity as compared to conventional farming [17]. The inclusion of these variables in our models was limited to the existence of high-resolution global maps. Multiple elements of soil biodiversity drive ecosystem functions across biomes. However, even a great shift in bacterial community structure may not always result in any significant change in overall nitrogen and carbon metabolism.

Arnold, London, Prescott LM, Harley JP, Klein DA (1996) The diversity of the microbial world. DGGE fingerprinting patterns showed a significant difference between the responses of culturable and total fungi communities under the stress of methamidophos. Akiyama et al. [109] reported that community level end points (measuring microbial activity and biomass) did not become affected by pesticide exposure, but on the other hand, subcommunity level endpoints (16s rRNA-based genotyping, T-RFLP, and PLFA composition) were affected by pesticide exposure, thus being better indicators to detect the changes in the resident microbial community caused by pesticides. In: Black CA (ed) Methods of soil analysis, part 2. Effects of biodiversity on ecosystem functioning: a consensus of current knowledge. In terrestrial ecosystems, soil functions are strongly linked to microbial community activities, which have a unique and indispensable effect on carbon (C) as well as nitrogen (N) cycling (Wieder et al., 2013; Sokol and Bradford, 2019).Soil microorganisms acquire C resources by discharging extracellular enzymes to decompose complicated small organic molecules, like labile or .

Data are presented as mean values standard errors of the estimated effect sizes. Hopkins FM, Torn MS, Trumbore SE. Further, soil C content correlated positively with both microbial biomass and microbial diversity, but correlations were much higher for the relationship between soil C content and microbial biomass than for richness (Fig. the display of certain parts of an article in other eReaders. Thus, using the samples with the highest sequence/sample yield, we tested for the impact of different levels of rarefaction on belowground diversity. 4).

These results are integral for us to predict changes in soil biodiversity globally, as C is highly threatened by climate change and land use intensification [70, 71]. However, it is not always the same and sometimes no significant changes in SMB are observed, which suggests that SMB alone may not be a good indicator in determining soil quality, particularly in low residue cropping systems such as cotton [36]. Increasing and diversifying global food demands are mounting pressures on agricultural production, and hence, are becoming major challenges to contemporary agriculture.

Nowadays, emphases are being given to develop green technologies that can degrade toxic pollutants already incorporated into nature in order to bring their levels down to what we consider safe. Reduces urease activity continuously while phosphatase activity seems stimulated but then reduces. Ros M., Goberna M., Moreno J.L., Hernandez T., Garcia C., Insam H., Pascual J.A. Root exudate components such as carbohydrates and amino acids act as stimulants and help plant growth promoting bacteria (PGPB) colonization through chemotaxis [80], a well-known mechanism for the establishment of interactions between soil microbiota and host plants within the rhizosphere [81]. The lack of local soil testing facilities led to blanket recommendations for crop nutrition in a blind race to increase yields. Banerjee, S. et al. However, firmicutes and proteobacteria were dominating classes on day twelve, indicating a halt in early opportunists growth and the initiation of re-establishment of a diverse population.

Managing Soil Quality: Challenges in Modern Agriculture. Herein, we hypothesize that soil C content is an important driver of the relationship between soil microbial diversity and biomass across global biomes [22] and that the microbial diversity-to-biomass ratio is an integrative proxy to know how diversity and biomass are interlinked. Makarian H., Poozesh V., Asghari H.R., Nazari M. Interaction Effects of Arbuscular Mycorrhiza Fungi and Soil Applied Herbicides on Plant Growth. However, unlike plant communities, little is known about how the diversity and biomass of soil microbial communities are interlinked across globally distributed biomes, and how variations in this relationship influence ecosystem function. Lugtenberg B.J., Chin-A-Woeng T.F., Bloemberg G.V. Toxic or ill effects of agrochemicals incorporated in soil knowingly or unknowingly in the course of various crop management practices can be remediated through application of potentially beneficial soil microorganisms. Flagella-driven chemotaxis towards exudate components is an important trait for tomato root colonization by. Second, in environments with higher soil C content, an increase in microbial biomass is potentially associated with the ecological displacement of non-competitive populations and a reduction of diversity (competitive exclusion; sensu Grace [6], Grime [7]), as proposed in plant communities [2, 4, 5, 9, 10] and local soil microbial communities [22]. 14, 29232936 (2008).

Conservation agricultural practices such as no-tillage (NT), also referred to as zero-tillage, and organic farming have improved soil health, namely, soil microbial diversity in general and soil microbial community stability in particular [28].

There is urgent need for ecologically sound agricultural advancement, which apart from being eco-friendly should also enable us to feed the ever-increasing population against the backdrop of ever-changing climatic conditions. As we are aware of the fact that changes in land use from grassland to agriculture affects the community structure [113], use of agrochemicals could be one of the important factors behind it.
